Thanks for the response and attempt at trouble shooting!
I had presumed it was just an issue with these two types of actors and how they do tend to act unique with behavior and settings
Including a screenshot for you.
The prefab forms and brings the actors into the list but aren’t visible. The two cubes floating there are the post process and physics i tried to bring in to cause them to load.
Also tried duplicating, show/hide. Nothing seemed to make them pop up.
